It features a 0.2570 inch cutting diameter, a 140-degree drill point angle with X-thinning geometry, and a TiAlN coating that extends tool life under high heat and friction. The helical flute design and right-hand cutting direction promote efficient chip evacuation. With an overall length of 3.5110 inches and a flute length of 1.4250 inches, this bit is suited for reaching into deeper bore locations where standard-length tooling falls short. It is installed by machinists and toolroom technicians working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for cross hole drilling, stack drilling, and general drilling operations across a wide range of workpiece materials. Primary material targets include steel and stainless steel. The bit also performs in superalloys, titanium, tempered steel, hardened steel, cast iron, carbon steel, structural steel, high-strength bronze, brass, copper, aluminum, and aluminum alloys. The 3xD flute-to-diameter ratio supports stable cutting at controlled depths. The cylindrical shank fits standard drill chucks and collet systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide construction with TiAlN finish for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with X-thinning and parallel web for reduced thrust and cleaner entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design for effective heat management and chip flushing at depth\u003c\/li\u003e\n  \u003cli\u003eHelical right-hand flutes with 3xD ratio for stable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eExtra length OAL of 3.5110 inches enables reach into deeper bore and cross-hole configurations\u003c\/li\u003e\n  \u003cli\u003eSuitable for cross hole, stack, and standard drilling operations across ISO material groups P, M, K, and N\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet toolholders accepting a 0.315 inch cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit from the toolholder. Verify shank seating and runout before beginning a cut. Follow the machine tool manufacturer guidelines for feed rate and spindle speed when working with carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 0.2570 inches (6.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5110 inches (89.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.4250 inches (36.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.0080 inches (51.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8180 inches (20.78 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0470 inches (1.19 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-Thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Cross Hole; Drilling; Stack Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITSUBISHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 662661\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51711585550642,"sku":"662661","price":181.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_7d80c142-8513-45eb-bbc0-f8e87684f5a8.jpg?v=1788477259","url":"https:\/\/voomisupply.com\/products\/mitsubishi-662661-extra-length-carbide-drill-bit-0-2570-in","provider":"Voomi Supply","version":"1.0","type":"link"}
